IMPROVED KN IFE-CLEAN ING- MACHINE.

The Schedule referred to in these Letters .Patent and making part of the same.

To all whom it may concern.;

Be it known that I, THOMAS-ROBERTS, of' Lynn, in the county of Essex, and State-'of Massachusetts, have invented a new and improved Machine for the Purpose o f Cleaning Knives and other Cutlery; and I do hereby declare that: the following is a. full and eX- act description thereof, reference being had to the accompanying drawings, and tothe letters of reference 'marked thereon.

c c are hollow tubes.

dis a roller, usually7 covered with woollcn fabric, upon which the knife rests. i

h is a common treadl'e, connected by. a rod with the wheels i i, which are connected wit-h the roller d and the perforated vessel b.

In working the machine, I place my foot upon the treale Il., working;r in the ordinary way, the Wheels fifi i causing the perforated vessel b to revolve, as also the roller d. Having turned the cock f, so as to allow the water to pass into the hollow tubes c, I lay the knife upon the roller (l. lhe process of cleaning the knife l* `is aided by the sprinkling of t-he brickflnst from the it, c, which is perforated on the under side.

l rests, and in which it turns. v

"This machine, when properly'constructed, is not only a convenience, but an ornament'to any house, `and takes up about as much room asan-ordinary sewing-machine.

I donot claim in vention in the construction or arrangement of the wheels '-i and 4treaalle h,- neither do I claim invention in the construction of either of the `vessels a, b, orc, separately and by themselves.

That I claim, as my invention "and improvement, `is

The airangement of the vessel @hollow tube c c, roller (Z, and perirated vessel l), as combined and arranged with the frame and tabie,'and the apparatus Vto `give motion to the machine, as shown .and descri bed.`
